Sustainability and efficient use of resources are becoming increasingly important aspects in the operation all industries. Recently, some biomass-fired boilers have been equipped with complex condensing back-end heat recovery solutions, sometimes also using pumps to upgrade low-grade heat. In kraft boilers, however, scrubbers still mainly for gas cleaning, only simple solutions. this paper, we ...

This paper deals with the application of state space neural network models to fault detection and accommodation of the boiler unit. The work describes two aspects. First one is the fault detection and in this paper to diagnose the fault the three methods are described and compared: simple and adaptive threshold and more robust method which is model error modelling. The second part of the paper ...

This paper presents a model predictive control (MPC) strategy based on genetic algorithm to solve the boiler–turbine control problem. First, a Takagi–Sugeno (TS) fuzzy model based on gap values is established to approximate the behavior of the boiler–turbine system, then a specially designed genetic algorithm (GA) is employed to solve the resulting constrained MPC problem. A terminal cost is ad...

A simple simulation using SIMULINK is presented to model the thermal/control behaviour of a domestic gas boiler. The simulation was the first step in a research programme to investigate the efficacy of control using an oxygen sensor. A brief review of boiler control is used to outline current practice and research developments. Ratio control in several forms has been investigated. Performance i...

The Pulverized Coal Fired Boiler is a control object with time-varying parameters, large delay and multivariate tight-coupling. This paper, aiming at improving the actualities of excessive parameters and suboptimal data clustering effect in the Steam Drum Pulverized Coal Boiler running, proposes a new algorithm Fuzzy Clustering Algorithm (APFM) to fulfill the efficiency optimization of the boil...

Relational transducers mapping sequences of input relations to sequences of output relations are proposed for high-level declarative specifications of business models. See [404] for a related class of ASM-transducers. Contains the problem description for the steam boiler control competition [7] and 22 proposed solutions obtained using the major known formal methods, with text and complete docum...

This paper presents an overview & current sources and forms of raw .materials for wood energy use and the types of machines available to convert them to the desired form for boiler fuel. Both the fuel source or raw material, and the combustion furnace will dictate the requirements for the processing system. Because of the wide range of processing equipment available, systems can be designed to ...

This paper focuses on the simulation and visualisation of coal combustion in the pulverised coal boilers. It is important to find optimal boiler configurations (both for the ecological and economical reasons), determine appropriate combustibles, optimize process of combustion, etc. These tasks are typically solved using traditional Computational Fluid Dynamics (CFD) methods that are in general ...

Centrifugal heat pump has to be coupled with gas boiler to supply high temperature water in radiator heating system. Regarding to hybrid heating system (HHS), operation strategy has significant impact on its annual energy consumption and cost. In this paper, the optimal operation strategy of the HHS composed of sewage-source centrifugal heat pumps and gas boilers was analyzed. Firstly, the perf...

One of the robust fault detection filter (RFDF) designing method is based on sliding-mode theory. The main purpose of our study is to introduce an innovative simplified reference residual model generator to formulate the RFDF as a sliding-mode observer without any manipulation package or transformation matrix, through which the generated residual signals can be evaluated. So the proposed design...
